Résumé :

Comparison of the levels of α1AT, α2-M, inter α-AT, C1 inactivator and antiplasmin and global antitrypsin activity in a group of normal phenotype PI MM individuals, a group of normal individuals with phenotypes with intermediate α1AT activities and two α2-AT-deficient persons show that α1AT contributes more than 90% of the total antitrypsin activity of normal plasma. AT III and fast reacting antiplasmin are shown to contribute to the remaining activity. It can be assumed that due to test conditions the antitrypsin activity of α2-M is not assessed. C1 inactivator and inter α1-AT do not contribute to a perceptible extent to the overall antitrypsin activity estimated according to the method of Eriksson (Eriksson, S. (1965) Acta Med. Scand. 177, 1). © 1977.
